If you're having issues with Redective where every search brings up "There was a problem retrieving the information. Did you type a valid query?", /u/8th_account has revealed a potential solution.

I also got the same problem but I can finally solved it by turning off the built-in Firefox tracking protection. Sometimes I got weird interaction with some websites and tracking protection is the culprit.

There was a problem retrieving the information. Did you type a valid query?

I've been trying it every couple days since I got my match for the latest round of Redditgifts exchanges. I get that same response for my own username, as well as any random username I try from any posts I read on Reddit.

HI there developer of Redective. First I just want to thank you for the neat tool. I included your tool in my weekly edition of Tool Highlight Tuesday where I walk other digital marketers through using the features of a tool. I dont have a big following, but maybe it'll drive some new users your way.

I had a question about the "hours" part that wasn't answered in the FAQ's. What time zone is that in?

I've had a few users tell me Redective is not working for them. When they attempt to search for anything, they receive the error:

There was a problem retrieving the information. Did you type a valid query?

Thanks to /u/Huntsmitch, I was able to deduce that the extension "Disconnect" causes the problem as it's blocking access to reddit, which Redective obviously needs to download information on users and subreddits. Simply enabling access by unchecking the reddit box under "Social" from within the extension is enough to get it working again.

If you're not running Disconnect and Redective still isn't working for you, please let me know.
